Title: Digital magnetic recording method
Inventor: KOIZUMI MAKOTO
IPC: G11B5/09
Filed: 1989-09-04
Abstract: PURPOSE:To prevent a head magnetized by setting magnetic field intensity by which AC erasure is performed at >= 750 times the saturation magnetic field intensity, and setting the number of times of dwindling of a recording current for self-demagnetization at every completion of recording at >= 30 times. CONSTITUTION:A recording circuit system is comprised of a recording amplifier 13, a timing circuit 14, a recording current dwindling circuit 15, and a recording control circuit 16, and recording data 17 is comprised of an effective data area 18 and a demagnetization data area 19. At such a case, the recording is performed by permitting the recording current 20 to flow on a head 10 to which the AC erasure is applied with an erasing magnetic field of 750 times the head saturation magnetic field intensity Hs in advance via the recording amplifier 13 by using a bulk eraser 9. The recording current 20 dwindles a current value at the demagnetization data area 19 by operating the recording current dwindling circuit 15, and a recording current dwindling circuit constant is decided so as to set the number of times of dwindling at 30 times. In such a way, the self-demagnetization of the head after recording effective data is performed.

Title: Power steering device and tube joint used for the same
Inventor: NAKAYAMA KOJI
IPC: B62D5/07
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To easily and quickly deal with kickback by incorporating a check valve in a flare nut for a piping seal inserted into the input port of a hydraulic control valve or the output port of a hydraulic actuator. SOLUTION: A check valve 30 permits pressure oil to be supplied to a hydraulic control valve 8 while its movable plug 32 is separated from the valve seat 31a of a casing 31, and prevents the reverse-flowing of pressure oil from the hydraulic control valve 8 to a hydraulic pump side while the movable plug 32 is tightly fixed to the valve seat 31a. Since a power steering device has the check valve 30 incorporated in a flare nut 20 inserted into the input port 8b of the hydraulic control valve 8, the full length of the input port 8b is shorter compared with the case where the check valve 30 is arranged separately from the flare nut 20. Thus, the increase of a valve housing 8a in size for dealing with kickback is prevented.

Abstract: PROBLEM TO BE SOLVED: To reduce power source capacity by a method wherein the value of printing duty corresponding to one page indicated by a printer driver is compared with the value of printing duty indicated to determine the number of printing passes for one page, thereby to control the number of passes. SOLUTION: A printer driver 101, which receives image information by means of an operation system on the side of an information processing device, effects a bit-map development of the image information in an internal memory in the information processing device by means of a bit-map development task 101A. And the printing duty obtained is sent from the device to a printer 102.
